RADIATOR CONSTRUCTION.

Specification of Letters Patent. Patgnted J 1145 29 191111 Application filed July 18, 1910. Serial No. 572,425.

To all whom it may concern Be it known that 1, JOHN E. GHATMAN, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Radiator Constructions, of which the following is a specification, reference being bad to the accompanying drawings.

This invention relates to improvements in radiator construction and particularly to improvements in radiator constructions which are used in what are called indirect radiator systems; that is, systems in which the radiator-stack is incased and is supported, as from the ceiling, the air being led to and from the casing.

An object of this invention is to provide a radiator construction of this type which may be readily and cheaply installed and the installation of which will cost very much less than in the case of indirect radiator systems now in common use. This low cost of installation is brought about in the following ways, namely: (1) The plates of sheet-metal which form the top, bottom, sides and ends of the casing for the radiator proper or radiator stack may be cut to standard sizes and no time and no stock will be wasted in cutting and fitting these parts; and the steam-fitter may do the work of incasing the radiator-stack and this work of putting up the casing will require much less time than it does by methods heretofore pursued. In the latter methods the casing built around the radiator-stack by a sheetiron worker, who first goes to the place of installation to take his measurements and then goes there a second time to build the box of sheet metal around the radiatorstack.

Another object of this invention is to provide a radiator construction of the type hereinbefore mentioned which will prove readily susceptible of repair and the cost of the upkeep of which will be very small. This reduction in the cost of repairs is accomplished in the following manner, namely: (1) The pipe-connections and connections for the hangers by which the structure is supported lie outside of the casing, where they are readily accessible for repair; and (2) the plates forming the top, bottom, ends and sides of the casing may be readily removed to expose the radiator-stack. All that is necessary to be doneto obtain access to the radiator-stack is to slip out one of these readily removable plates; and this plate is just as readily replaced. Of course, any of the casing plates may be so removed and replaced. In my new construction it is not necessary to cut the plates of the casing, in order to fit these plates around the pipe-connections and hanger connections; for, these connections are so placed as to do away with such cutting and fitting.

Briefly described, my new radiator construction comprises a radiator-stack and a casing therefor. The radiator-stack is built up in the usual way but the outside radiatorsections are preferably formed with sideframes cast integral therewith, although the outside radiator-sections may be of the usual pattern or type and the side-frames made separable from them. These side-frames are slotted and grooved to receive the sheetmetal sides, top, bottom and ends of the casing which incloses the radiator-stack and are provided with pipe-connections and hanger-connections which are so located as to avoid the slots and grooves which are formed in the side-frames and in which lie the edges of the sheet-metal casing plates. In addition to the advantages above set forth, my new radiator construction possesses the further advantages of always presenting a workmanlike appearance and also of eliminating poor workmanship; for, these casing plates being cut to size, they are always sure to fit accurately and to provide the proper amount of air-space.

In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure l is an end elevation and Fig. 2 is a side elevation of my new radiator construction, a part of the casing being broken away to disclose the interior; Fig. 3 is a horizontal section on the line AA of Fig. 2; Fig. l is a perspective view of my new radiator construction, a part of the casing being shown broken away; Fig. 5 is a detail in horizontal section which shows on an enlarged scale the construction at one side of the radiator structure; Fig. 6 is a fragmentary detail which shows in perspective the construction of an integral side frame; Figs. 7 and 8 are fragmentary details in perspeestruction, in which the sidecframes are sepa rable from the'ra-diator proper or radiatorstack; Fig. 12 is a section on the line BB- .ofFig. Fig-13 is a fragmentary detail in perspective of one of the detachable sideframes'shown in Figs. 10 to 12, inclusive; and Fig. 14 illustratesin horizontal section a modified form of my invention in which an extra long radiator-stack is used.

Theradiator-stack or radiator proper consists. of the side radiator-sections an, a and the intermediate radiator sections a. These radiator-sections are assembled or connected with one another in the usual way. vVith the side radiator-sections a, a are formed integral the side-frames Z), 7) respectively. The side-frame b'consists of the standards or'corner-piecesc, the top cross bar (Z and the bottom cross-bar e, which cross-bars connect the upper and lower ends,

respectively, ofthese corner-pieces 0. Similarly, the side-frame 6 consists of the standards or corner-pieces 0, the top crossbar d and the bottom crossbar e, which crossbars connect the upper and lower ends, respectively, of these. corner-pieces 0. These corner-pieces c, c extend above and below the radiator-stack a distance suflicientto provide the necessary air-space f and are formed with lengthwise-extending grooves g, h in their longitudinal edges' The end wall of each corner-piece is formed near its top and just below the upper cross-bar d with a transverse channel. or open-ended slot 2' and is further formed near its lower end and just above the lower crossbar 6 with a similar transverse or horizontal channel j. In the'side wall of each corner-piece there is a hole 70. through which projects one, end of a supporting-bar m and a hole n through which extends an end of a tie-rod 0. The tierods 0 extend from side to side of the radiator-stack and just above the same, while the supporting-bars m lie parallel with the tierods 0 and, of course, just below theradiatorstack. 'In each side wall 0 of each cornerpiece a istapped a hole 22 which is adapted to receive a pipe-connection whereby provision is made for the inflow and outflow of the circulating fluid as hot-water, steam,

or the like, or in case the apparatus is used for cooling, brine, ammonia, etc.) but both of the pipe-connections 9 may be carried by the samecorner-piece 0*, as is shown in Fig. 4. The end of each supporting bar m passes throughanceye formed in the lower end of ahanger-bar 1' and this lower end lies between the nuts 8, s screwed on the projecting end of the supporting-bar m. The upper ends of the four hanger bars 7' are fastened I being deemed capable of suiting thesup porting devices to the exigencies of the circumstances presented by the particular case.

Plates of sheet-metal are used to form a casing for the radiator-stack. The topplate a, the bottom-plate v and the end-plates 'w will be made preferably in standard sizes, which will depend upon and vary with the number of radiator-sections used in building up the radiator-stack, of course. As is best shown in Fig. 7, the bottom end-edge or horizontal edge of each end-plate w is formed with an inwardly-projecting flange w; and as is best shown in Fig. 8, the end edges of the top-plate u are formed with downwardly-extending flanges it. In buildslipped into the upper slots or recesses i in the two corner-pieces of one of the sideframes. The end-plates w are next slipped into place in the side-frames with their side edges or vertical edges sliding in the grooves.

flat is next ushed into lace in a manner 4 7 a n y quite sim lar to the way 1n WlllCll the top-- plate u was positioned, the corner parts of.

the bottom plate resting in the lower recesses j formed in the lower ends of the corner-pieces c, c and its end edge-'portions-lying below the flanges w formed on the bottom of the end-plates w. are then pushed into place; but it may be remarked that these side-plates may be put in place at any time andfwithout any re gard whatever to the positioning of the other plates u, e, and w, The lower crossbars 6, e serve to assist in supporting the bottom plate 4) and the latter in turn assist in supporting the end-plates w. The bottemplate 0 is formed with an opening adapted to receive the discharge end of the cold-air pipe y, 'while the top-plate u is formed with a similar opening in whichfis adapted to fit the intake end of the hotair pipe 2 (shown only in Fig. 4); but, of

course, these pipes may, to suit the requirements of any particular case, be inserted in other plates of the casing, one of the pipes communicating with one of the air-spaces f and the other pipe with the other air-space 7', all in a manner well-known to those:

skilled in this art. p I V The upper and lower cross-bars d, e of the mg up the casing, the top-plate u is first 7 ice The side-plates V a, a may be formed with the integral corner-pieces 2 shown in Fig. 9. These cornerpieces may, however, be made separate from, instead of integral with, the outside radiator-sections, as will be perfectly obvious from an inspection of Fig. 9.

Instead of forming the side-frames integral with the outside radiator section (the construction shown in Figs. 1 to 6, inclusive), separable or detachable side-frames 3 (Figs. 10 to 13, inclusive) may be used, if desired. The corner-pieces at of the sideframe 3 shown in Fig. 13 are formed with longitudinally-extending grooves 5, 6, in their edges and are joined together by the integral top cross-bar 7 which is L-shaped in transverse section and in the edges of which are grooves 8, 9. The lower ends of the end-walls l are connected by the integral lower cross-bar 10 the inner edge of which is grooved, as at 11, and the outer edge of which lies within the inner face of the end wall 4" of the corner-pieces 4, whereby the ready insertion of the sideplates as into the open lower ends of the grooves 5 in the side-walls 4" is permitted. The top-plate u is pushed from one end into the grooves S in the top cross-bars 7 of the side-frames 3 and the end-plates w are then forced upwardly into place with their vertir-al ei lges sliding in the grooves 6 in the end-walls l of the corner-pieces i. Finally the bottomplate o is pushed into place from one end of the structure, a pair of its edges sliding in the grooves 11 of the lower crossbars 10 of the side-frames 3. As before the side-plates 00 may be positioned at any time without regard to the other plates.

The corner-pieces 4 may be made separate from each other by merely dispensing with the metal of the crossbars 7, 10 which join a pair of these corner-pieces to make up a sideframe. By omitting this metal, a cor ner-piece construction closely resembling that shown in Fig. 9 results. Either one of the cross-bars may be omitted, while retaining the other.

\Vhere the radiator-stack is built up of many sections and is, therefore, extraordinarily long, some of the intermediate sections. as a may be formed with ribs 12 which are grooved to receive the edges of the end-plates As shown in Fig. 14, the latter are made up of four parts; but, of course, the number of sections (4* may be made as great or small as the length of the radiator-stack demands.

In the case in which the side frames are formed integral with the outside radiator sections, it is to be observed that these integral. side-frames are the only parts of the radiator-stack which are exposed to direct contact with the body of air forming the outer atmosphere; and to prevent too rapid radiation and to reduce the radiation loss It is wholly immaterial as to what fluid is passed through the radiator-stack,

whether steam, hot water, brine or other heating or cooling liquid or gas. Hence, the arrangement of parts herein shown may, without the exercise of invention, be used with perfectly obvious changes for a system of cooling.

Changes may be made in the details of the radiator construction hereinbefore described, without departing from the spirit of my invention. For example, the casing plates may be made of material other than sheet metal and the walls of the casing may be fastened to the frame-members in ways other than that hereinbefore described (e. 9., these walls may be bolted to the framemembers). These changes and all others of a like character are deemed by me to be within the scope of my invention.
